A collaborative roading plan worth more than $1.2 billion, put together by the Otago and Southland regional councils, has laid out priorities for southern roading.
Residents of the regions have until March 6 to make submissions on the draft Otago-Southland regional land transport plan.
The Otago Regional Council and Environment Southland collaboration includes proposals for everything from separated cycleways on State Highway 1 in Dunedin to work in North Otago to provide flood protection.
Other projects include improvements in the Frankton Flats area of the Wakatipu Basin, and an upgrade of the link between penguin viewing sites in the Catlins area.
The plan includes all state highway and council projects for Southland and Otago for the next six years proposed for funding from the National Land Transport Fund, which is administered by the New Zealand Transport Agency (NZTA).
Recommended spending for Otago transport projects from 2015 to 2018 is $435 million, and $423 million for 2019 to 2021.
For Southland, the figures are $218 million for 2015 to 2018, and $221 million from 2019 to 2021.
Otago regional transport committee chairman Trevor Kempton said local authorities had chosen to fund about $40 million of the work.
Projects of significance to both regions would benefit from combined advocacy whereas, in the past, plans were focused within each region, he said.
Most were already part-funded by the NZTA, with the rest to be considered by the agency.
